nomor 22 & 23 yang di centang pliss bantu aku

22. f(x) = x, g(x) = x^2-6x, h(x) = 7-3x
a. (fog)(x) = x
(fog)(x) = (x^2-6x)
(gof)(x) = x^2 - 6x
(gof)(x) = (x)^2 - 6(x)

b. (foh)(x) = x
(foh)(x) = (7-3x)
(hof)(x) = 7-3x
(hof)(x) = 7-3(x)

23. f(x) = 3x+5, g(x) = 2x, h(x) = x^2+2
a. (fog)(x) = 3x+5
(fog)(x) = 3(2x)+5
(fog)(x) = 6x+5

b. (goh)(x) = 2x
(goh)(x) = 2(x^2+2)
(goh)(x) = 2x^2 + 4

Semoga membantu yaa:)
